Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
Because it is glucose-dependent, this class carries a low intrinsic hypoglycaemia risk on its own — the risk arrives when it is combined with insulin or a sulfonylurea, which usually need reducing.
What I am after is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Numbers rather than impressions, if you have them.

Insulin sensitivity test (HOMA-IR) on glycaemic control — arguably the most important metabolic marker most people aren't tracking:
HOMA-IR = (fasting insulin × fasting glucose) ÷ 405
My numbers: Baseline HOMA-IR = 4.9 (insulin resistant) → Current = 1.1 (insulin sensitive)
Anything above 2.0 indicates insulin resistance. The goal is below 1.5. GLP-1 agonists address the root metabolic dysfunction, not just the symptoms. This is why they work so much better than calorie restriction alone.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 118 | 100 | 90 | 84 |
| Insulin (fasting) | 24 | 14 | 10 | 7 |
| HOMA-IR | 4.5 | 3.9 | 1.8 | 1.2 |
| Uric Acid | 8.6 | 6.8 | 5.7 | 4.9 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 4.5 to near 1.0 is a metabolic transformation.

Can confirm. Same sequence, different timescale. Nothing to add that would improve it.

PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 7 months: periods became regular for the first time in years, testosterone levels normalized, acne cleared significantly, and — unexpectedly — I got pregnant naturally after 4 years of trying.
GLP-1 agonists address the insulin resistance at the root of PCOS. For PCOS patients, this isn't "just" a weight loss drug — it's treating our underlying metabolic dysfunction.
